OneDrive for Business Stuck in Read-Only Mode (OD1017081)

We've completed deploying the permanent fix to the affected infrastructure, and after a period of monitoring, we've determined impact is now resolved.

We’ve successfully deployed the permanent fix and anticipate it will be completed by Monday, March 3, 2025. Additionally, the targeted rollouts intended to provide immediate relief for the second scenario are currently 93 percent complete.

We've initiated the targeted rollouts for immediate relief for the second scenario, which are currently 50 percent complete. In addition, we've completed development for our permanent fix which is undergoing deployment with an expected completion date of Monday, March 3, 2025.

We're continuing to validate our interim fix for scenario 2 and are in the process of initiating our first wave of targeted rollouts. In parallel, we're developing and testing our permanent fix which will address this issue for all users. We'll aim to establish an estimated time to deploy the fix in our next scheduled update.

We've developed a fix to address scenario 2, in which newly licensed accounts aren't registering in our internal systems as expected, and we're performing internal validations before applying it more broadly. We expect that this process will begin by our next scheduled update. In parallel, we're continuing to monitor responses confirming resolution from users who received our fix for scenario 1, which addressed the unsupported configuration we outlined in our last communication.

We've investigated further and determined that your users may experience impact behavior due to several scenarios, which require separate mitigations.

Scenario 1 - Users may be in a read-only state due to account ownership being moved from an individual to a group, which is an unsupported state. This state can be mitigated by following the instructions outlined in the 'More info' section of this communication. If you've followed these steps then, while the banner informing users that they're in a read-only state remains, users can edit content as expected. The fix we've been tracking has also been specifically targeting this scenario, and we've fixed approximately 93 percent of accounts in this state. These accounts will no longer see the read-only banner.

Scenario 2 - Users may be in a read-only state due to issues registering licenses for accounts that were recently licensed. Since accounts are perceived as unlicensed, users are put in a read-only state. This issue was introduced when we reverted a portion of code in an attempt to remediate the first scenario, and we're working to develop a remediation strategy to address this secondary impact.

We've confirmed with some sample affected users that our change successfully provides relief, and we're in the process of applying it more broadly. We anticipate that our fix will complete and remediate the issue by our next scheduled communications update.

We've collected a preliminary list of accounts in unsupported states and we're validating our change, which will be applied to these accounts to alleviate impact by reversing the policy enforcement rollout. This alleviation is temporary, as the configuration our policy rollout interacted negatively with is an unsupported scenario. Please refer to https://learn.microsoft.com/en-us/sharepoint/manage-user-profiles#add-and-remove-admins-for-a-users-onedrive to ensure account ownership is properly configured to prevent future impact. We'll aim to provide an estimated timeline to resolution in our next scheduled update.

Our rollback of read-only sites is progressing as expected in a thorough and secure pace for our previously identified use cases. While we continue our mitigation efforts, we strongly recommend admins to take prompt action and perform the self-mitigation steps outlined in our “More Info” section as our changes may not address every unique configuration of OneDrive owners who have been changed from the correct Entra ID owner. We’ll continue rollbacks and provide another update on Wednesday, February 26, 2025 at 4:00 PM CST

We’re continuing our rollback to remove affected users and sites from the read-only state that they are in. In addition, we’ve expanded our initial use case scenarios to include other potential scenarios that may result in similar impact. Interim, admins should change their configurations from unsupported states as described in the more info section.

We’re analyzing and expanding additional use case scenarios where this read-only issue can affect users to ensure they're included in our mitigation efforts. This quick update is designed to give the latest information on this issue.

We’ve confirmed the cause of this issue was as a result of a recent policy change in our enforcement of unlicensed OneDrive user accounts, which uncovered unsupported instances of users being removed as admins from their own OneDrive accounts and further resulting in read-only status.

We’ve paused the rollout of this enforcement change to prevent new users from entering this bad state or being archived and are working on rolling back affected users, which we anticipate completing within the next week. In addition, we’ve provided links with instructions in the more info section if you would like to manually revert the read-only state and resolve these unsupported states within your organization more quickly.

We received reports of an issue where some users' OneDrive for Business content is in read-only mode and an error states "You can't edit your files because your license to use OneDrive ended over a month ago." We're reviewing these reports to determine our next steps.
